Definitions

the invention relates to an offset printing unit with a blanket cylinder, a plate cylinder and an inking cylinder having a flexible working surface, which are all driven at the same speed, and an anilox roller supplying ink to the inking cylinder.
the inking cylinder has a diameter corresponding to the effective working diameter of the printing form, that is to say the plate cylinder covered with one or more plates, and rotates at the same surface speed and in the area of the contact point with the same direction of rotation.
the invention has for its object to provide a printing unit of the type mentioned, in which a grinding movement between the plate cylinder and the inking cylinder is minimized.
the printing unit shown comprises a blanket cylinder 1, which sits firmly on a shaft 2.
the shaft 2 is mounted on both ends of the blanket cylinder 1 in a side wall 3.
a gear 4 is still firmly attached.
a plate cylinder 5 interacts with the blanket cylinder 1.
the plate cylinder 5, together with a gear 6, is firmly placed on a shaft 7, which in turn is mounted between the side walls 3.
an inking unit which has an ink pan 8.
a screen roller 10 seated on a shaft 9 is partially immersed in the ink pan 8.
a doctor blade 11 is provided for stripping off the excess ink from the anilox roller 10.
an inking cylinder designated overall by 12
the inking cylinder sits together with a gear 13 on a shaft 14.
the gears 4, 6 and 13 have the same pitch circle diameter and the same module, so that the cylinders 1, 5 and 12 rotate at the same speed.
the inking cylinder 12 has a diameter of approximately 99 percent of the diameter of the plate cylinder 5.
a layer 16 of an elastic ink-accepting material is applied to its solid core 15, the thickness of which is 2 to 3 percent of the diameter of the inking cylinder 12.
the layer also has a hardness of 60 to 70 ° Shore. It expediently consists of rubber or a similar material which is used for the production of rubber blankets.
the layer 16 is expediently vulcanized onto the ink application cylinder 12.
the teeth of the gearwheel 13 are designed with a negative profile shift.
the shaft 14 is supported by an adjustable eccentric bearing 17 in the side wall 3 and in the same way in the opposite side wall.
the eccentric bearing 17 By means of the eccentric bearing 17, the inking cylinder 12 can be placed on the plate cylinder 5 during operation such that it is in contact with the plate cylinder 5 in the circumferential direction over a length 1 of approximately 7 to 9 mm.
